Circuit Breaker Test Equipment Information
Circuit breaker test equipment is equipment designed for testing and analyzing the function of circuit breakers to ensure they are operating properly and within specification. They are used to ensure that circuit breakers are operating correctly. These circuit breakers perform the basic function of connecting and disconnecting electrical power, which can be DC, or AC either single or three phase power. The test equipment ensures that the circuit breaker will connect and disconnect the load from the power source as they are intended to. This also means they need to disconnect at certain fault situations and ensuring they do this correctly is important.
To perform these tests the equipment will apply power to a circuit breaker, and tests various aspects such as the current, voltage , contact resistance, switching time, frequency, and perhaps simulate a fault, as well as other tests. These tests results are then provided to determine if the circuit breaker is function as it is supposed to.
Some equipment will perform these tests automatically while other equipment requires the operator to perform various operations to complete the tests. Once the test is complete the results can be provided in any number of ways such as on a display screen, via analog meters, printed out or sent as data to a computer.
